14413 Geiger           Discovered 1991 Sept. 5 by F. Borngen and L. D. Schmadel at Tautenburg.
German physicist Hans Geiger (1882-1945) studied radioactivity and scattering of \alpha -particles. Together with Erwin Wilhelm Mueller, he invented the GM (Geiger) counter, which became an important measuring instrument in nuclear physics. Together with K. Scheel, he edited the 24-volume Handbuch der Physik (1926-1929).
